The lightest, most compact closed-cell mattress is now warmer than ever: a new, aluminized surface reflects heat, increasing overall warmth by nearly 20%. The proprietary foams are softer on top for extra comfort and denser on the bottom for extra durability. Wherever you’re headed, the Z Lite Sol mattress is the right choice for ultralight, warmth, durability and comfort.*Due to popular demand we are continuing to offer the original Z Lite™, without the reflective barrier, in the Coyote pattern.*
